How to choose the right switching transistor for my application? It must withstand the current, generated heat and applied voltages. Current and voltage does not pose any problem. You have to use some calculations about the power dissipation. (more…)
I bought a digital thermometer DS18B20 and I wanted to connect it to my LaunchPad. DS18B20 communicates via 1-Wire protocol. I used a bit banging to emulate the protocol. CPU speed should be over 1 MHz since the protocol requires timing almost on a microsecond level.
